2. The AOA probe values show a constant DC offset between L & R, that is not consistent with a AOA failure, that looks horribly like an installation error. There is no other way as far as I can recall from my own B735 AMM, that you can get a constant variation between the output, from an faulty vane, it will be jammed, or otherwise inoperative but it doesn't have a constant offset between the two systems.
What work was done on the aircraft prior to despatch on the AOA system?
very early in the lionair thread in pprune , the issue of installation error was discussed- thrashed and a few diagrams of hole arrangements a to avoid improper install were dug up/published here .
supposedly arranged to avoid such a problem of ' clocking'- since the same unit is used left and right.
